CABLEWAY.

Original application led March 18, 1909, Serial No; 484,101. Divided and this application led October Patented July 23, 1912.

17, 1910. Serial No. 587,449.

To all whom it may concern:

Be it known that I, THOMAS SPENCER MIL- LER, a citizen of the United States, and a resident of South Orange, county of Essex, and State of New Jersey, have invented a new and useful Improvement in Cableways, of which the following is a specification.

My invention relates to new and useful improvements in cableways and more particularly to a load carriage for use in connection with cableways in which fall rope carriers are employed, the object being to provide a carriage with improved means for picking up, discharging and carrying the fall rope carriers.

This application is a division of my prior application filed March 18, 1909 and serially numbered 484,101, in which I have disclosed and claimed a fall rope carrier alone, and a load carriage in combination therewith, the load carriage being the same as that forming the subject matter of this application in which it is intended to claim the carriage without regard to any particular form of fall rope carrier, as said carriage may be readily employed with other carriers not of the particular form shown in said application Serial Number 484,101.

In the accompanying drawings, Figure 1 is a side view of a load carriage constituting my present invention, a fall rope carrier and the coperating ropes of a cableway of the class above referred to. Fig. 2 is an end view of the fall rope carrier. Fig. 3 is an end view of the buffer of the load carriage against which the fall rope carrier rests. Figs. 4 and 5 represent the fall rope carrier in action. Figs. 6 to 11 are details.

1 is the main cable; Q, 2, the hoisting ropes; 3, the traversing or traction rope; 4, the button-stop-rope, all of which are supported and operated in the manner and by the means well known.

5 is the main frame of the load carriage constituting my present invention, the same carrying the wheel G and a pivoted equalizing frame 7 carrying the wheels 8, 9 and 10. The wheels 6, 8 and 9 run upon the main cable and the pivoted frame 7 enables the wheels 8 and 9 to adjust themselves to the inclination of the cable. The hoisting rope sheaves 11, 12, are mounted upon the main frame 5. The wheels 10 on the pivoted equalizing'frame 7 engage the button-rope, as shown.

13 is a frame movable upon the main frame, being pivotally Vconnected thereto upon a pivot bolt as shown at 14. The function of this frame is to support the horn 15 and the buffer 16. I desire it understood that while I have shown and described the frame 13 as being pivoteol on the main frame, I do not limit myself to that construction as any means `for mounting the frame or the wheel 2l, so as to permit free vertical movement of the same comes within the spirit and scope of my invention.

17 is a wheel shown in detail in Figs. 10

and 11 and which runs upon the main cable 1. This wheel carries the frame 18 and has an adjustable bearing therein. This wheel 17 maintains approximate parallelism between the horn 15 and the main cable; the variation from such parallelism at various points on the cable being so limited as not to interfere with the proper operation of the horn. Vhether the cable is loaded lightly or heavily, and whether the load carriage is at the middle or the end of the span, the horn is thus self-adjusting in position which I regard as of great importance particularly in `a high speed cableway.

-In order to' provide for adjustment between the wheel 17 and the frame 13, which adjustment is essential to compensate for wear of the wheel 6 or wheel 17, I provide an eccentric bearing 18 for the wheel 17, as clearly indicated in Figs. 10 and 11. This eccentric bearing is mounted upon the pin 19 passing through the frame 13, and the wheel 17 turns freely upon the eccentric bearing in whatever position it may be adjusted. The eccentric bearing is keyed to the frame 13 by a key 20. There are several notches in the frame at various points of the periphery of the pin 19 to receive this key, as shown in Fig. 10, and by removing the key, turning the eccentric bearing ,18, and inserting the key in another notch, the eccentric bearing may be adjusted and fixed in any posit-ion desired.

21 is a wheel mounted on the frame 13 and bearing upon the top of the button-rope 4.

The purpose of the wheels 21 and l() is to maintain parallelism between the buttonrope and the cable. y

2Q a safety wheel that may be employed to prevent accident due to the abnormal lifting of the frame 13 b y an undue strain on the button-rope il.

The buffer 1G in the form shown in the drawing, is constructed of wood or other soft material. It is fixed to the pivotal frame 1.3 at 23 above the button-rope and at Q4. It is fixed to the horn at lt is provided with openings to permit the passage of the horn l5 and the cable l. lt is also provided with the holes to permit the passage of the hoisting ropes 2, 2a and traction rope 3; also, with the hole l0 reinforced by a plate 39 to admit the passage of the button-rope et; also7 with pockets 28a, E27 and 28a to receive the fall rope carrier sheaves E2G., 27 and 28 lying against it, as shown in Fig. l.

In order that the operation of the carriage will be fully understood I will now describe one form of fall rope vcarrier in connection with which it may operate. the same being the form claimed in my said prior application, although l desire it understood that the carriage may be used with other forms of fall rope carriers with satisfactory results.

Between the body A of each fall rope carrior and the body B of its cooperatingl button, is introduced an impact member C, being the member which, is to receive primarily the impact of the collision between the fall rope carrier and the button. This impact member is provided with a lostmotioirconnection with the part upon which it is mounted. The lost moti-on thus introduced at the moment of impact between the body of Athc carrier and the body of the button or stop relieves the force of the blow by ving 'the body of the carrier time within which to lose its momentum.

ln the form of construction shown in Athe drawings, the impact member C shown as molmted upon the fall-rope carrier itself but it might be mounted upon the bottom or stop or on the button-rope. ln the form shown in the drawing, the lost-motion-connection is between the impact member and the body of the fall rope carrier and it consists, as there shown, of a vibrative connection capable of bowing under the force of the impact and thus affording the reop uisite lost motion. More specifically, still., it consists of a Vpivotal connection between the impact member C and the carrier body A. More specifically, still, it consists of the two pivotal connections l) and E between the body of the carrier body A and the impact member C. These two pivotal connections are afforded by pivoting upon the pin 29 the

uprights

30 and 31 connected at the top by the pin 32 and hanging the impact member C pivotally upon said pin 32 u between said uprights 30 and 3l. ln the particular form of construction shown in the drawings, the lost-motion-return, or, in other words, the return of the impact member to its normal position, is produced automatically by the tension (generally produced by a counterweight) on the buttonrope 4l, and is completed by the impact of the buffer 16 against the carrier as it is picked up on the horn by the return of the load carriage.

33 is 'the horn-block in the form of a saddle adapted to rest on'the horn. It is fixed to the body of the carrier by the bolts Q9 and 34.

35 is the main cable block also in the form of a saddle adapted to rest on the main cable.

26 is the sheave by which the rope 2 is carried when slack.

2T is the sheavc by which the rope 3 carried when slack.

28 is the sheaye by which the rope 2 is carried when slack.

lt will be understood that the pulleys or

sheaves

26, 27 and 28 serve to support the ropes 2a, 3 and 2 respectively when the fall rope carriers are detached from the frame and distributed along the cableway.

The sheave 36 is provided above the sheave 2G so that if the rope 2a should be raised by extreme tension as high as the main cable, it will not carry the carrier along with it. rEhe same function is performed by lthe friction sheaye 37 with re spect to the rope 3. The eyes B of the sucH cessive rope-carriers of a scribes will be graduated in size, as shown in Figs. 7, 8 and 9, so as to cooperate with the corresponding graduation in the size of the buttons by which they are respectively to be stopped.

The operation is as follows: ln Fig. 4, l have shown two fall rope carriers in the position which they occupy when being carried on the horn of the load carriage; the carriage receding so that the eyes of tho fall rope carriers are approaching the but-- ton-stop B. ln Fig. 5 the load carriage has receded about the length of the horn; the result being that the button 38 has passed 'through the eye of the first carrier (such eye being large enough to permit its passage) and has collided with the eye of the second carrier (such eye being too small to admit of its passage). The shock of the collision has caused the head to vibrate upon the body A and the eye to vibrate upon the head into the position shown in Fig. 5. During the movement of the carriage along the main cable the horn 15, is at all times maintained in proper position to support and carry the fall rope carriers so that the latter will not be dislodged from the horn except when they strike a stop on the stop rope, or to pick up and hold the carriers, according to the direction in which the carriage is moving, the wheel 17 preventing the dropping of the horn below proper position and the safety wheel 22 preventing the horn becoming elevated too high.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l.
